1. Serum proteins from sarcomatous soft shell clams, Mya arenaria L., enhanced transmission of sarcoma. 2. Sarcoma cells were isolated and administered to the recipients at the same cell density in different sarcoma-protein-free diluents: seawater, serum from normal clams, heat-treated sarcoma serum
Transmission experiments with adult soft-shell clams (Mya arenaria) demonstrated that clam sarcomas are transmissible with hemolymph from neoplastic animals but not with cell-free ultrafiltrates. Non-neoplastic clams were injected with either hemolymph from neoplastic clams or a cell-free
Seasonal and geographic studies of transmissible sarcoma in Maryland softshell clams, Mya arenaria, were carried out from 1984 to 1988. Three major epizootics occurred in our sampling location during this time, resulting in prevalences as high as 90%, with comparable mortalities in other high
1. Serum proteins showed quantitative and qualitative differences between sarcomatous and healthy soft shell clams, Mya arenaria L. 2. Total protein concentration was significantly higher in the serum of sarcomatous clams than of healthy clams. 3. According to SDS-PAGE, more serum proteins with more
